ABSTRACT: Chaocipher is a method of encryption invented by John F. Byrne
in 1918, who tried unsuccessfully to interest the US Signal Corp and
Navy in his system. In 1954, Byrne presented Chaocipher-encrypted
messages as a challenge in his autobiography =E2=80=9CSilent Years=E2=80=9D=
. Although
numerous students of cryptanalysis attempted to solve the challenge
messages over the years, none succeeded. Chaocipher has been a closely
guarded secret known only to a handful of persons. Following fruitful
negotiations with the Byrne family during the period 2009-2010, the
Chaocipher papers and materials have been donated to the National
Cryptologic Museum in Ft. Meade, MD. This paper presents the first full
disclosure and description of Byrne=E2=80=99s Chaocipher algorithm......
